Product Details anti-TNF alpha Antibody

Characteristics: Neutralization Activity: This antibody has been reported to be useful for the neutralization of recombinant human TNF. Neutralization activity may be measured using a cytolysis assay for MTT dye conversion with 2.0 ng/mL recombinant human TNF (Cat. No. 554618) and L929 at 2 x 10^5 cells/mL as indicator cells (i.e. preincubation of the antibody with recombinant human TNF for 60 minutes).
50% Neutralization (ND50) at 1 -100 ng/ml
>90% Neutralization at 50-300 ng/mL

Purification: The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.

Alternative Name: TNF

Background: The MABTNF-A5 antibody, formerly known as 5N, reacts with human tumor necrosis factor, TNF (aka, TNF-alpha and TNFSF2). TNF is a multifunctional cytokine involved in a variety of immune and inflammatory responses including hemorrhagic necrosis of tumors, septic shock, fever and autoimmune diseases. TNF can regulate the growth and differentiation of many different cell types. It is produced by different activated cell types including macrophages, T lymphocytes, NK cells, dendritic cells, endothelial cells, peripheral blood leukocytes, osteoblasts, astrocytes, mast cells, Kupffer cells, smooth muscle cells, fibroblasts and certain tumor cells. TNF exists in two biologically active forms, i.e., transmembrane and soluble forms. Upon activation, cells express transmembrane TNF glycoproteins that associate as homotrimeric complexes. After enzymatic cleavage, the extracellular region of membrane TNF sheds as a soluble homotrimer. The biologically active form of TNF has been reported to be a trimer. The immunogen used to generate the MABTNF-A5 hybridoma was purified recombinant human TNF. This is an extraordinarily potent neutralizing antibody that is reportedly also useful for ELISA measurements of human TNF.
